1.0 Introduction
The ACU2 is a compact, 48 kHz digital and audio distribution module that connects remotely
located operator stations and live radios to the ACENet network. The ACU2 is compatible with
the Telestra and Voisus platforms. The ACU2 provides low noise, analog-to-digital conversion,
and low-latency audio distribution.
The ACU2 integrates press-to-talk (PTT) units, volume controls, simulated communication pan-
els, hand-held terminals (HHTs), and live radios into the simulated communications envir-
onment.
The ACU2 supports the following features:
lStereo support: stereo operation (i.e., independent left and right output) is supported on a
single DB-15 connector, which reduces cabling complexity and installation footprint for
applications requiring stereo operators.
lCompact footprint: each device supports four configurable mono or stereo operator pos-
itions in a single compact unit, which fits easily on a desktop. Alternatively, rackmount
two devices side by side in 1U 19" rack space.
lHigh fidelity audio: 48 kHz digital audio and balanced pro-audio interfaces.
lSoftware-based configuration: software-adjustable amplifier or preamplifier gains and
microphone power for easy, direct connection to military and commercial headsets and a
wide variety of audio and communication systems and peripherals.
lSerial data ports: control interface for ASTi HHTs, simulated panels, and live radio con-
trol.
lIntegrated I/O: configurable digital and analog input/output (I/O) for direct connection of
PTT units, volume control, switch detection, radio PTT activation, and other control
applications.
